Abstract (en)
[origin: US2006274839A1] A method and system for adaptive control of sub-carriers is useful for increasing frequency diversity gain to improve bit error rate performance in an Interleaved Frequency Division Multiple Access (IFDMA) system. The method includes selecting a combination of a Repetition Factor (RF) and a repetition block size (Q), from possible combinations of a RF and a Q, based on a number of users (N<SUB>u</SUB>) (step 1405 ). A Spreading Factor (SF), Forward Error Correction (FEC) coding rate (R), or modulation order (M) based on the N<SUB>u </SUB>is then determined (step 1410 ). Control signals are then provided based on the RF and Q, and based on the SF, R, or M (step 1415 ).
